One of the oldest rivers in the world, the Susquehanna (Siskëwahane) stretches for 444 miles from Cooperstown, NY, to the Chesapeake Bay. For millennia, the river has been an important waterway and water source for human communities. Its history is recorded in countless poems, stories, and songs by modern and ancient Pennsylvanians. Geologically and hydrologically, the river is connected to over half of Pennsylvania's watershed and landscape.
